Be it known that I, J OHN FRICK, acitizen of the United States, residing at Philadelphia, county of Philadelphia, and State of ennsylvania, have invented a new and useful Improvement in Coin-Controlled Dispensing-Machines, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, which form a part of this specification.

The object of my invention is to provide an improved form of coin-controlled dispensing device adapted to deliver successive portions of food or other articles upon the insertion of a coin or a predetermined number of coins totaling the amount tof'becol lected.

- Referring to the accompanying drawings, in which I have illustrated a preferred embodiment of my invention and in which like symbols refer to like partsin the various views Figure 1 is a side elevation of the delivery shelves. Fig. 2 is a front elevation of the delivery shelves.

Fig. 3 is a detailed view, partly in section, of the. actuating mechanism.

Fig. 4 is a view on line 44 Fig. 3. Fig. 5 is a horizontal section through the machine.

Fig. 6 is a side elevation of the machine, partly in section.

Upon the base a and within a casing b is mounted an inclosed shaft or chamber having a front wall 0 of glass let into the casing and provided with an aperture at its lower end adjacent the base. Theside walls are formed from solid pieces 6, while the rear is closed'by a door 7. A dumb waiter, comprising shelves 71 (the lower one of which is provided with an apron secured between uprights j, is adapted to work up and down in the shaft, the uprights being guided by' pieces 70. A series of cams Z, Z are secured to the outside of one of the uprights j.

A hand lever m extends through the cats ing and is pivoted to a bracket 1 secured to the inside of the casing. The lower arm of the lever is cgnnected to one end of a hollow plunger 0, adapted to Slide horizon- Speclflcaflon of Letters Patent. I

this application filed d retains the handle in normal position. A

rod g on a line with plunger 0, but normally spaced therefrom, is supportedobynew and adapted to slide in a bearing 1'. end of the rod q is pivotally connectedto a.-

link 8, the other end of which is pivoted to an arm t, the pivot pin carrying a roller vu adapted to underlie one of the cams Z, as shown in Fig. The other end of arm 21 is'pivoted .-toa bracket '0. Al hanger w, provided with'a series of holes :12 adapted to carry a pin 1 which in normal position chute-2 and blocks or. stops the chute, is secured Ito rod 9 by means of a: set screw ,guided by a guide slot. A link pivoted to the lever m is connected to the hanger adjacent rod 9 by a slotandfp'in connection.

A coin slot 3, inthe' caslng, communicateswith a chute 5 adaptedto easily carry a coin of predetermined size and is provided, on its under side, with apertures 6, just narrower than the coin for which the chute is adapted. The cover of the chute is provided with holes 7 for'inspection urpos'es and for extracting any'coin w 'ch' might become jammed. The lower end of the chute opens above the space between the end of the hollow plunger 0 and the An opening is provided in the base a enters one of the holes 2 in the wall of a beneath chute '2, communicating with a coin box 9.

The open end of plunger 0 is mag- .netized to divert any slugs or fake coins from chute 2, as indicated at 11, cau'sing them to drop directly into the coin box and}.

not form a connection for the actuating mechanism.

In operation, the dumb waiter shelves h are supplied, through door 7 at the back, with the article to be dispensed and the dumb waiter raised to its upper position, where it is maintained by the engagement of roller u with the under side of the lower cam Z, there being a pair of cams Z, Z for each shelf.

.The machine may be set to vend, the articles for any number of coins, the amount charged determining the number, as, for example, if the price of the articles is ten shown in Fig. 3, so that the mechanism will not become operative until two nickels have been deposited.

To operate the mechanism, a. nickel is inserted 1n the slot and travels down the chute 5 between the ends of plunger 0 and rod 9, into chute 2, resting on' the pin 3 the pin being set as in Fig. 3. A second nickel is deposited and comes to rest on top of-the first squarely between plunger 0 and rod q. The hand lever m is then depressed, causing the plunger 0 to move forward and engage the nickel between its end and the end of rod 9. Continued movement causes rod to move, which movement is conveyed to roller to through link 8 and arm t, causing the roller to move toward the point of cam l. The hanger w moves with the rod 9 causing pin 3/ to be withdrawn from chute 2 and permitting the coin or coins in the chute to drop through the opening in the base a into a coin box 9. As the roller u reaches the point of cam Z, the plunger 0 is stopped by contactin with the edge of the bearing 1*. The weig t of the dumb waiter trips the roller off the point of the cam, giving the rod 9 a slight independent motion which releases the coin forming the connection between plunger 0 and rod 9 and permits it to drop through the opening in the base into box 9. The dumb Walter descends under its own weight and cam Z strikes the roller, forcing it back under the next cam Z, which it engages, stopping the waiter with the first shelf h flush with the lower edge of aperture d in the front of the shaft through which the articles on the shelf may be withdrawn. The backward movement ofroller I u is transmitted to rod 9 through link 8 and arm t, causing rod 9 to move backward; and the coin forming connection between plunger 0 and rod 9 having been released, it telescopes within plunger 0. The handle, being released, is brought back to normal by means of spring 9. This movement of the handle, through link 10, causes hanger w to return to normal, with pin y extending into chute 2. v

The apparatus is then in position to repeat and bring all of the shelves 7?. opposite the aperture in the front of the shaft, successively.

It will be obvious that the number of coins required to operate the mechanism may be changed and regulated by the positions of pm 1 Should any fake coins be inserted in the apparatus, as, for example, slugs or washers having central holes, the actuating mechanism will not be connected since the end of rod 9 is of a size to penetrate such holes and depression of lever m would: result merely in telescoping of the rod ii -plunger o. The

entering chute 2. The diverted slugs will dropthrough the mechanism as shown at 11,

and fall outside of .chute 2, directly into the v coin box. I The chute 5, will not accommodate coins larger than the predetermined size and smaller coins will drop out of the chute through apertures 6 in the under side of the chute.

I do not herein claim the details of the coin-controlled apparatus, as the same forms the subject-matter of an application filed by me December 3, 1919, Serial No. 342,161, g

of which this application is a' division. I

Having now fully described my invention,

what I claim and desire to protect bybLetters Patent is 1. In a coin-controlled dis ensing machine, the combination with a umb waiter,

of a member having a groove and a plurality of stop seats, a spring actuated stop within the groove adapted to arrest the descent of the waiter at a number of different vertical positions when in engagement with either of said seats and also movable out" of supporting relation therewith to allow it todescend from one vertical position toanother,

means to withdraw the stop out ofsaid supporting relation, manually-operable mechanism, a coin receiver ad'aptedto receive and so position a coin that the coin acts, in the operation of said mechanism, to form an operative connecting link between said mechanism and the stop-withdrawal means, and

cams on the grooved member to shift the stop against the action of its spring to permit the dumb waiter to be freely raised.

2. In a coin-controlled dispensing ma-- chine, the combination with a dumb waiter, a series of pro ections thereon and a series of cams thereon, of a stop normally engaging one of said projections and thereby holding the waiter from descent, coin-controlled and manually-operable means to displace said stop from supporting position,

said stop being movable by one of said cams, in the descent of the released waiter, into position to engage the next projection and thereby arrest the descent of the waiter.

3. In a coin-controlled dispensing machine, the combination with a dumb waiter,

of a series of projections thereon arranged I one above another, a series of cams thereon arranged in staggered relation with the projections and providing a zig-zag path for the stop hereinafter mentioned, a pivoted stop normally extending under a projection to support the waiter, coin-controlled and manually-operable means to swing said stop from under a projection and into the path of the cam immediately above it, said cam, in the descent of the Waiter, swinging the stop back into position into the path of the next projection of the series.

4. device of the character described comprising a cam member with a race having a plurality of stop seats in spaced relation, and a spring actuated movable stop within said race arranged to arrest the movement of the cam in one direction when the stop is in engagement with any of the cams in the cam member seats, said race being shaped to permit the stop to move freely in the reverse direction and shift the stop against the action of its spring during such movement.

5. In a coin-controlled dispensing machine, the combination with a dumb waiter, of a series of projections thereon arranged one above another, a series of cams thereon arranged in staggered relation with the projections and providing a zig-zag path for the stop hereinafter mentioned, a pivoted stop normally extending under a projection to support the waiter, coin-controlled and manually-operable means to swing said stop from under a projection and into the path of the cam immediately above it, said cam, in the descent of the waiter, swinging the stop back into position into the path of the next projection of the series; the cams and the projections are provided with upper cam faces, thus allowing the waiter to be freely raised and in the course of its ascent causing the stop to vibrate back and forth until it settles beneath the lower projection of the series.

In testimony of which invention, I have hereunto set my hand, at Philadelphia, Pa, on this 14th day of May, 1920.
